  1. BANNED! But Is There Still Hope?

    The collection of ornamental fish in Hawaii: BANNED. The collection and sale of live rock and coral from Fiji: BANNED. The permits for shipping coral, anemones and live rock from Indonesia: HALTED and now going on its second month. Two major bleaching events in the Great Barrier Reef leading to an estimated loss of 50% or more of the coral cover during two of the last three years. Needless to say these headlines do not produce a whole lot of optimism about the long-term prospects for the...
  2. Jamie Craggs’ Game Changing Work at the Horniman Museum

    Over the years I have witnessed a lot of breakthroughs in the hobby. In terms of propagating corals we have gone from barely being able to keep most corals alive to the point where we can now propagate most corals through some form of fragmentation. Some of these advancements we have achieved have allowed for some damaged reefs to be repopulated by corals that have been “grown out” away from the ocean. In this regard, we should take pride in what we have been able to accomplish and how if...
  3. Chasing Coral opens eyes, by documenting coral bleaching

    As reef keepers, we know precisely what causes bleaching. Within coral tissue lives photosynthetic zooxanthella algae. To maintain coral health, a delicate balance must be maintained, ensuring the zooxanthella don’t grow too quickly, but that they can always photosynthesize and provide the coral with any additional nutrition.
  4. Spreading The Goods: Giving Coralline Algae A Kickstart

    Coralline algae is a very beneficial life form that most reefers want in their tanks. It can come in many colors and some even forms interesting branching shapes. It can encrust on just about anything. After a while, cleaning it can actually become an extra task on the weekly maintenance list. For those of you who are not to this level of growth or just starting a tank there is a great way to get those white rocks as purple as a grape.
  5. The significance of reef tank lighting; a semi-scientific documentary.

    With the constant debates about different lights and which is better, I figured I'd share a recent experience. Many people believe lighting is everything, and expensive lights will keep expensive corals. Many other people believe that water parameters and husbandry play the biggest role. And the majority of people probably fall somewhere in the middle and agree that you can't value one over the other; they are all important and need to be given equal attention. This article will look at a...

  7. The Pros and Cons of Aquacultured vs Maricultured vs Wild Coral Colonies

    Visiting MACNA or any of the large frag swaps or shows 10 years ago the vendors present for the most part displayed large wild colonies of coral under metal halide lamps. IN the last five years this has changed dramatically as now almost all of the vendors show frags of corals under blue LEDs. So this begs the question: why have things changed so dramatically in such a relatively short time? Have hobbyists become more conscientious in terms of not wanting to take colonies from the ocean and...
  8. Source Water: Choosing Your Salt Mix

    Tenji is pleased to present a series of exclusive articles for Reef2Reef members. We will be delving into the various aspects of reef keeping, focusing on tried and true methods that can be implemented by aquarists of all levels. Once you are producing 0 TDS water from your RO/DI system it’s time to create the ideal reef water by mixing in a synthetic salt. Choosing your salt...
  9. We play nature's game...

    As some of you might know, I’ve done a little “pivot” away from the business end of the reef hobby world, to focus on my other aquatic obsession, blackwater aquariums. Doesn’t mean I’ve abandoned reefkeeping. Nope. Just put my business focus on a different challlenge. It was funny, when I announced that I sold my interest in Unique Corals and started my own FW gig,some of my daily readers were sort of freaked,thinking,"Old Fellman's lost it and gone off the deep end!" Which, of course, I...

  13. Algal Filtration In Reef Aquariums

    With modern reefkeeping, more people are wanting to filter their tanks the same way that all natural reefs (and lakes and rivers) are filtered, which is by using algae. We are going to look at the main types of algal filtration methods you can put on your system: Algae turf scrubbers (ATS) Chaeto reactors (algae reactors) Refugiums (“fuge”) All grow macroalgae, which for our purposes is the same as “macro” or “algae” or “seaweed,” and all can be DIY’d or purchased. We at Santa Monica...

    Sometimes it's really all about the silver linings. I mean, I'm not the worlds most emboldened optimist - trust me, but in the wake of a devastating circumstance, I think if we can find just one flake of positivity, then at least we can't consider it a 100% failure. I have often considered the “first crash” an essential rite of passage in every reefers journey. Whether by malfunction, equipment failure, direct human error, the result of pests, or some other quirk we never discover, this...

  21. Newly discovered marine fish species to be named after President Obama

    The process of declaring a new fish species isn’t as simple as the outlook of one, or even a team of marine biologists. It will take time, DNA tests and a close inspection of the fish’s physical details and physiology before a formal scientific name is applied. Considering the fish is of the genus Tosanoides (a species previously thought to only occur around Japan) it’s likely the final name will be Tosanoides obama or some variant of that.
  22. Gone Fishing (Fish Collection)

    Have you ever wondered why marine fish are so expensive? Unlike a cichlid, or most other freshwater fish, marine creatures live in much harder to reach areas of the world. Some live hundreds of feet below sea level which is very out of reach to the Average Joe, thus it is more expensive to obtain these creatures. Not only are they harder to get to but they are also more difficult to capture. Yeah, people could just throw a hook and bobber over the reef but the odds of capturing the fish in...
  23. Child Proofing Your Aquarium

    As aquarists we all take great pride in the tanks that are in our care. Many of us also have small children who share in the enjoyment that a reef tank can bring. The aquarium can have a soothing effect on children and can spark their interest into things that may not be something they would have a chance to interact with where they live. With this in mind there are also some things with the aquarium that can be dangerous to small children like electricity, plumbing and chemicals. Even with...

    Hello all. Some of you may recognize me from Nano-reef and my posts about LEDs, DIY recommendations, etc. Figured I'd post this up over here, as well. Putting it in general hardware and lighting because it applies to more than just LEDs. :) With full-spectrum LED arrays becoming all the rage nowadays for better coloration, more and more people are considering them, but I see people saying all the time "dude, but corals only use blue light for all their energy and red only helps algae grow,...
  25. Reacting to Loss of Power: By cdness

    Reacting to Loss of Power In this day and age we rely on electrical power for many things. In this hobby all of the equipment used to sustain life depends on electricity including lights, pumps, powerheads, and controllers. If the power goes out the life support systems are terminated and the countdown timer to disaster begins. This article will describe the different ways an aquarist can protect the living creatures in their care in the event of power loss. DISCLAIMER: Please note,...
